[1] Charles Watts took charge of the publishing business and toured the country, delivering hundreds of lectures on theological, social, and political issues.

His wife, Kate Watts, often travelled with him and also wrote pamphlets, including The Education and Position of Woman and Christianity: Defective and Unnecessary.

Charles Watts then became the leader of the secularist movement in Canada, founding and editing Secular Thought in Toronto, and also regularly went on lecture tours of the US.

His son, Charles Albert Watts, who was later buried with him, remained active in the secularist movement, helping to develop the Rationalist Press Association.
